WINDING MACHINE.

Application filed November iary frames carrying the cop driving rolls also. independently manually movable, out of the way.

Another object is to provide means whereby the driving roll shaft is driven at a constant speed and the traverse mechanism cam shaft is driven at a variable speed.

My invention more particularly includes a winding machine in which the auxiliary frames each carry a rail' section, a kicker shaft section a driving roll shaft section, a plurality of driving rolls, their roll stands and a plurality of stop motions .and their rack bars, which rack bars are detachably secured to their respective cop holders and which driving roll shaft sections are detachably coupled together, the movement of the cop holders and the auxiliary frames, out of the way of the cams and cam shaft being permitted by detaching the rack bars from their cop holders, uncoupling the driving roll shaft sections and kicker shaft sections and unfastening the auxiliary frames from the main frame.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Fig. 1 represents in side elevation so much of a winding machine as will .illustrate my improvements.

Fig. 2 represents a detail end view of the machine, showing the drive for the several parts.

'Fig. 3 represents a through the machine, with the parts in the positions they assume when starting the winding operation. Fi 4 represents a similar view with the cop olders and auxiliary frames swung out of the way for gaining readyaccess vertical cross section 20, 1924. Serial No. 751,017.

to the traverse mechanism cams and shafts.

Fig. 5 represents a detail view showing an intermediate coupling for the cop driving roll shaft.

Fig. 6 represents a cross section on the line VIVI of Fig. 5.

Fig. 7 represents a detail vertical cross section showing a tube holder, as distinguished from the cone holder, illustrated in the other figures. v

Fig. 8 represents a detail section taken ii the plane of the line VIII-VIII of In thepresent instance I have shown the machine as provided with two rows of cop holders 1, of usual construction, independently mounted to rock on the bar 2 extending lengthwise of the main frame 3. Each of these cop holders 1 is provided with the usual depending arm 4, to which arm is removably attached the usual stop motion rack bar 5 as, for instance, by providing the free end of the depending arm 4 with a pin 6, arranged to enter a hole in the inner end of the rack bar 5, a flat spring 7, carried by the arm 4, serving to hold the inner end of the rack bar 5 on its pin 6. Thisconstruction will permit the ready detachment and removal of the rack bar 5.

The usual traverse mechanism cams 8 for reciprocating the thread guides 9 are carried by the cam shafts 10, rotatably mounted in the main frame 3, and means are provided for rotating these cam shafts at a variable speed, as distinguished from a constant speed, as hereinbefore common,

which means is constructed, arranged and operated as follows:

The main drive shaft 11, herein shown as driven from'an electric motor 12, carries a. cone pulley 13 which drives through a belt 14 an opposed cone pulley 15, carried by a shaft 16 suitably mounted in the main frame. This shaft 16 carries a worm 17 which meshes with a gear 18, carried by an arm 19 projecting from the main frame. A pitman rod20 connects the gear 18. with the slide 21 of a belt shifter, which belt shifter is provided with an arm 22, engaging the belt 14., The slide 21 is mounted to reciprocate on a suitable bracket support 23 of the main frame. A train of gears 24, 25, 26 connects the worm shaft 16 withthe camshaftslO,

This arrangement causes a variable speed to be imparted to the cam shafts .10, .10,

from the drive shaft 11, by the shifting ofv the belt 14 along the oppositely coned pulleys 13, 15, through the pitman rod connection 20 between the gear 18 and belt shifter slide 21.

The usual cop driving rolls 27 along each side of the machine, are carried by a sectional driving roll shaft 28. Each end of each shaft section is removably attached to its adjacent alined section by a coupling 29, certain of the couplings 29v being provided for by dividing the cop driving rolls, as shown in Figures 5 and 6. Each driving roll shaft section also carries several of the driving rolls 27 and it is rotatablymounted in the usual roll stands 30, uprising from a rail section 31, forming part of an auxiliary frame, the depending arms 32 of which are pivoted near the rail section to brackets 33, carried by the main frame 3. To hold these auxiliary frames in their operative position the free ends of the depending arms 32 are bolted or otherwise secured at 34 to fixed bracket arms 35, carried by the main frame.

.These auxiliary frames carry the usual stop motion mechanisms including the rack bars 5, hereinbefore described and the kicker shaft sections 43, each attached to its adjacent alined section by the-cou ling 44.

One of the sectional driving roll shafts 28 is driven at a constant speed from the drive shaft 11, through the pulley 36, belt and pulley 38. The other sectionaldrivmg roll shaft 28 'is driven at a constant speed from the drive shaft 11, through the pulley 39, cross belt 4.0 and pulley 41.

Divided cam covers 42, 42 are carried by their respective auxiliary frames with their edges interlocked when the parts are in their operative positions.

hen, for any reason, it is desired to gain access to the traverse mechanism cams and cam shafts the desired rack bars 5 are detached from their co holders 1, the desired cop driving roll s aft sections are uncoupled, the' desired stop motion kicker shaft sections are uncoupled and the depending arms 32 of the auxiliary frames-are unfastened from their-bracket arms 35. The released colpeholders may then be swung upwardly yond their normal inoperative osition, out of the way. The auxilia ofthe wa taking withfiithem their cam covers. ese positions of the cop holders and auxihary frames areshown in Fig. 4 of the drawings, where it will be seen that very ready access may be obtained to the cams and cam shafts without dismantling the machine, as has heretofore been nry.

It is evident that various chan may i be resorted to in the construction, cm and arrangement of the several parts without ry carryin ames may then be swung outwardly, out.

departing from the spirit and-scopeof my invention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is:

1. In a winding machine, a main frame, a

thread guide reciprocating cam shaft carried thereb an auxiliary frame, and a cop driving rol shaft section carried thereby, said auxiliary frame being movable out of the way, for gaining ready access to the cam shaft.
